I have not had these tweezers for very long, so I can’t speak to their longevity yet, but they very much work the way they should about a month in to owning them. I’m hoping that I don’t have to purchase another pair, but as long as they last me several years I think they will be worth the cost. More expensive upfront, but cheaper when I consider all of the cheaper tweezers, I’ve purchased and discarded over a couple years.
